public class extrafields extends activity{      button btnsubmit;      int nooffields=0;        @override     public void onbackpressed() {         // todo auto-generated method stub         super.onbackpressed();         finish();     }      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         this.requestwindowfeature(window.feature_no_title); // removes title bar         this.getwindow().setflags(windowmanager.layoutparams.flag_fullscreen,                 windowmanager.layoutparams.flag_fullscreen); // removes bar          setcontentview(r.layout.extra_fields);          btnsubmit = (button) findviewbyid(r.id.submit);          btnsubmit.setonclicklistener(new onclicklistener() {             @override             public void onclick(view arg0) {                 // todo auto-generated method stub                 nooffields = 0;                  send();             }         });     }         protected void send(){      }   }

    cb= (checkbox)findviewbyid(r.id.checkbox1);      if(cb.ischecked()) edittext t = (edittext) findviewbyid(r.id.edit4); string = t.gettext().tostring();      }
